STEERING (CONT)
CAUTION
To prevent damage to power steering pump
during performance of step f, do not allow load
valve to be closed for more than 5 seconds.
f. With engine idling, close load valve and read pressure gage. Pressure
must be 900 to 1000 psi (621 to 690 kPa).
If pressure is less than 900 psi (621 kPa), repair (page 19-2)
or replace power steering pump (page 7-2).
Step 3. Check for sufficient pump flow as follows:
a.
Perform steps a thru e of step 2.
W A R N I NG
Maximum flow rate is 7 gpm (26.5 liters/rein).
Flow rate in excess of 7 gpm (26.5 liters/rein)
will damage steering gear and could cause loss
of steering and injury to personnel.
b. With engine idling, read flow meter. Rate of flow must be 7 gpm
(26.5 liters/rein).
Repair (page 19-2) or replace power steering pump (page 7-2).
c. With engine idling, close load valve until pressure gage indicates pump
relief and pump relief pressure drops to 0. Immediately open load valve.
Flow rate must return to 7 gpm (26.5 liters/rein).
Repair (page 19-2) or replace power steering pump (page 7-2).
d. Run engine at 2100 rpm and fully close load valve until pressure gage
indicates pump relief and flow rate drops to 0. Immediately open load
valve. Flow rate must return to 7 gpm (26.5 liters/rein).
Repair (page 19-2) or replace power steering pump (page 7-2).
Step 4. Check for defective teflon seals in steering control valve.
Repair (page 19-8) or replace steering gear (page 7-4).
